Salivary Cortisol (Three Specimens), MS (Endocrine Sciences)
Use
Salivary cortisol measurement is an important tool for assessing adrenal function and circadian rhythm disturbances. It is especially useful in diagnosing disorders such as Cushing's syndrome and Addison's disease. By measuring cortisol levels at three different time points, healthcare providers can evaluate the cortisol production profile, aiding in the diagnosis and management of endocrine disorders. This test is non-invasive and convenient, suitable for patients who need cortisol assessment throughout the day.
Special Instructions
Not provided.
Limitations
The test is developed by LabCorp and has not been cleared or approved by the FDA. While it provides valuable insights into cortisol levels, results should be interpreted in conjunction with clinical findings and other diagnostic procedures. Variability in saliva collection methods or timing can affect results, and the stability of samples is influenced by environmental conditions during collection and storage. Freeze/thaw cycles may impact the accuracy of cortisol levels measured.
